Step 1
Look closely for moth infestation in bathrooms because they enjoy living in laundry baskets, natural bristle brushes and linen closets. Look for tiny holes in clothes, towels or linens, which can indicate a moth infestation. Shake brushes onto white paper and watch for small moths that are buff colored to fall from the brush. They are about half an inch in length.
Step 2
Check the bathroom areas at night by utilizing a bright flashlight. Adult moths will fly towards the flashlight, indicating that there is a moth problem. Turn all lights off in the bathroom for a few hours and then shine the flashlight into the areas in question and watch for tiny moths.
Step 3
Watch for damage to carpets around the toilet, shower or bath because these are a common area for foot oil to build up. The moths lay eggs in the organic oil that is left behind by human feet and bodies. When the larvae hatch they will feed on the organic oils in the carpets, which will result in damage to the inorganic part of the carpet.
Step 4
Inspect the corners of the bathroom, molding and crevices. These are favorite locations for moths to lay eggs and for larvae to emerge because hair buildup in a bathroom is common from brushing, trimming and washing hair. Small amounts of hair built up in these locations make them ideal places for moths to flourish.
Step 5
Purchase pheromone based insect traps at any local home improvement store and place them in the closets of the bathroom closets, the drawers, the clothes hamper, or near the toilets. These will not kill eggs or larvae, and they rarely attract female moths, but male moths will flock to the traps. Check the traps the next morning for any signs of infestation.
